Hello,
You can put the banner anywhere on the Internet that you want...but you have to refer to it relative to its exact location, rather than how you have it in the template now.
It looks like your IMAGE tags all refer to things like: src="Resources/jnk0001tnew1a.jpeg"
While that is fine if you are already on YOUR web site where the Resources folder exists... Out on eBay or on the web you need to specify the exact HTTP: location of the image file.
Sorry to be long winded...just wanted to give you an understanding of what is going on...
Anyway, in your template if you want to have Auctive host your picture, change this section:
<img src="Resources/jnk0001tnew1a.jpeg"
To something like...:
<img src="http://img.auctiva.com/imgdata/1/8/8/1/1/6/webimg/[file]_o.jpeg"
If you upload your pictures to Auctive and then go to the Manage tab you will see that there is a URL associated with each picture. That will be the actual text that you'll want to substitue.
For part #2 of your question... If you want to show the picture...then you'll need to put another IMG tag in the HTML of the Template text...
As for the digital product, I'm not familiar enough with that to give you an answer...
Hope that gets you started...
Mike
